U.S. Army Regimental System


The United States Army Regimental System is an organizational and classification system used by the United States Army. It was established in 1981 to replace the Combat Arms Regimental System to provide each soldier with continuous identification with a single regiment, and to increase a soldier's probability of serving recurring assignments with their regiment. The USARS was intended to enhance combat effectiveness by providing the opportunity for a regimental affiliation, thus obtaining some of the benefits of the traditional regimental system.

Overview

USARS was developed to include all combat, combat support, combat service support, special branches, and training battalions in the Regular Army, Army National Guard, and Army Reserve.
It was developed to offer the opportunity for long-term identification with a regiment or corps, provide the potential for recurring assignments within a regiment or corps, provide the opportunity to further emphasize the history, customs, and traditions of the regiment or corps, and provide regiments that are structured as one or more continental United States units of like type linked with one or more units of like type outside the continental United States, or one or more units of like type located exclusively in either CONUS or OCONUS, including one or more training battalions or tactical armored cavalry or ranger regiments.
USARS is also designed to provide for CS, CSS, and special branches to operate on a “whole branch” concept as a corps or special branch, carrying on the activities and traditions of a regiment, offer regimental affiliation to allow soldiers the opportunity for continuous identification with a combat arms regiment, a corps, or special branch throughout their careers. USARS provides different opportunities for soldiers, depending upon which combat arms regiment they choose to be affiliated with or whether they affiliate with a CS or CSS corps or special branch. In addition, the regimental affiliation process allows combat arms soldiers to select the regiment of choice ; provides that CS, CSS, and special branch soldiers will automatically be affiliated with their corps or special branch; specifies that all soldiers will belong to a regiment or corps; permits no limit to the number of soldiers who can be affiliated with a regiment or corps; and provides that DA civilians can automatically be affiliated with a regiment or corps by direction of the regiment or corps commander.

Combat arms

Concept

Combat arms is a rescinded doctrinal term, though colloquially it includes air defense artillery, armor, aviation, cyber, field artillery, infantry, and special forces regiments. Combat arms soldiers may affiliate with any of the combat arms regiments consistent with their primary military occupational specialty, specialty code, special qualification identifiers, or additional skill identifiers. Soldiers will have greater opportunities to serve recurring assignments in their regiments if regiments are chosen that have battalions in both CONUS and OCONUS locations. Since there is no ceiling on the number of soldiers who can affiliate with a particular regiment, the potential for recurring assignments to regiments is diminished where the number of affiliated soldiers exceeds the requirements.

Affiliation policy

Quoting from Chapter 3–2, page 7 of Army Regulation 600-82, U.S. Army Regimental System
:
a. USARS regiments offered to active Army and USAR soldiers for affiliation are listed .
b. Specific procedures for affiliation are below. These procedures permit affiliation and change of affiliation to be administered at the local Personnel Service Center level.
c. Active Army soldiers who are accessioned into the USAR will retain their regimental affiliation unless they elect to change their affiliation, which may be done at any time.

Combat arms regiments

Note: There are currently 178 USARS regiments, with only 47 consisting of units at multiple locations. Some of the regimental battalions are assigned to brigade combat teams in multiple divisions. Only 27 of these regiments meet the USARS "Conus/Oconus goal."
Additionally, the term "Regiment" was not officially appended to a USARS regiment's official name/designation until 2005.

Artillery regiments

Air defense artillery regiments

Field artillery regiments

Armored and cavalry regiments

Armored regiments

Cavalry regiments

Aviation regiments

Cyber regiment

Though a combat arms branch, the Cyber branch was not established until 2014 and does not trace lineage to any Army regiments under the Combat Arms Regimental System. The Cyber regimental plan is identical to that of combat support, combat service support, and special branches.

Combat support (CS), combat service support (CSS), and special branches

Concept

The CS, CSS, and special branch regimental plans fully integrate into the USARS under the "whole branch" concept. It is the responsibility of all proponents to incorporate within their corps, the intent and spirit of the regimental system to provide soldiers the opportunity for affiliation.
While this initiative mandates a uniform approach to regimental affiliation throughout the Army, it is a system that has no tradition within the Army and duplicates the sense of affiliation that CS, CSS, and special branch soldiers already had for their branch
